Filed: 1991-04-18
Abstract: PURPOSE:To speed up and simultaneously to prevent the slow down of the operations during a low voltage operation by controlling the gate of a load driving MOS transistor through the use of the in-circuit signal which has a higher amplitude than the output amplitude. CONSTITUTION:First, power supplies VSS and VCC of an inverter circuit consisting of MP4 and MN4, which drive a load capacitor CL, separate from power supplies VSL and VCH of the circuit which drives the inverter circuit and make the voltage value VSL be lower than VSS and make VCH be higher than VCC. As a result, the gate voltage of the MOS transistor, which drives the load capacitor CL, becomes large, eliminate the effect of the threshold voltage of p MOS MP4 and a high speed operation is realized. Furthermore, when power supply voltage becomes lower than 1.5 volts, a stable operation is realized without lowering the threshold voltage.

Abstract: PURPOSE:To improve the distribution of potential of a winding, to reduce an electric field applied to each section of the winding and to enhance insulating performance by making the thickness of an insulating sheet wound on the outer circumferential side of the winding thicker than that of an insulating sheet wound on the inside of the winding by stages. CONSTITUTION:A winding is constituted on the outside of the winding of an insulating sheet 2 in thickness of d1 by an insulating sheet 2' so that wall thickness is made larger than the insulating sheet 2 relatively and insulating thickness is brought to d2. When the insulating sheet 2' reaches near the outer circumference of the winding, an insulating sheet 2'' and a metallic sheet 1 are lap-wound so that wall thickness is made larger than those d1, d2 of the insulating sheet in the winding-start and central section of the winding relatively and insulating thickness is brought to d3. Consequently, the product L.C of inductance L and electrostatic capacity C in each section of the winding is kept constant, the winding is not vibrated, and the winding is not vibrated to the sudden occurrence of a surge, thus improving the distribution of potential of the winding. Accordingly, the distribution of potential of the winding is enhanced, and surge voltage characteristics are bettered with the enhancement of the distribution of the potential, thus improving reliability on insulation.

Title: Method of etching mesa groove on semiconductor wafer
Inventor: ITOU HITOSHI
IPC: H01L21/3063
Filed: 1978-07-17
Abstract: PURPOSE: To form mesa grooves of uniform depth in a base, by providing a mask on an epitaxial layer, converting the exposed part into an oxide film by anode oxidation and then removing it, and applying the same process on a base, when mesa grooves are to be formed in a base through an epitaxial layer whose thickness is not uniform.  
     CONSTITUTION: N-type GaAs epitaxial layer 22 is grown on high-resistance GaAs base 21. A plurality of mesa grooves are formed through layer 22 in base 21 by etching. In this drawing, the thickness of layer 22 is not uniform. Hence, the depths of the mesa grooves produced in this way are difficult to become uniform. For this reason, photoresist mask 23 is formed selectively on layer 22, layer 22 is impressed with voltage 24 and it is exposed to radiation by light 25 and thus anode oxidation is operated; after the exposed part of layer 22 is converted into oxide film, it is removed. After this, voltage 24 is impressed on base 21, and in a similar manner, oxide film 26 is produced inside base 21, and then this is removed. By this,  mesa grooves of uniform depth are formed in base 21.
